Detachable ammunition supply device for toy gun

ABSTRACT

The ammunition supply device for a toy gun is detachably plugged in a chamber of the toy gun&#39;s body. The ammunition supply device contains a transmission module and a loading module interacting with the transmission module. The chamber stores the BBs and the loading module of the ammunition supply device loads the BBs for firing by the toy gun. After firing, the ammunition supply device can be conveniently removed and it is assured that no BBs are remained in the toy gun. With the present invention, a toy gun of increased capacity, convenient assembly, and enhanced safety is achieved.

(a) TECHNICAL FIELD OF THE INVENTION

The present invention is generally related to toy guns and more particular to a detachable ammunition supply device for a toy gun.

(b) DESCRIPTION OF THE PRIOR ART

Generally today's rifle contains parts such as barrel, body, stock, grip, trigger, magazine, etc. However, for old-fashioned rifles before World War II, most of them do not have magazines and usually contains only body (with built-in barrel), grip, and trigger.

As electrical toy guns are design to be just like real guns, the electrical toy guns simulating the old-fashioned pre-World-War-II rifles therefore do not have magazines as well.

A partial sectional diagram of one of these electrical toy guns is shown in FIG. 1. As illustrated, a channel 921 for the accommodation of BBs is configured in a chamber 92 of the body 91. With the help of an elastic element (not shown), the electrical toy gun is capable of repeated firing without the re-supply of BBs after each shot. However, as can be seen from FIG. 1, there is little space for the BBs. When the BBs are run out, the body 91 has to be dis-assembled to remove the chamber 92, BBs are deposited in the channel 921, and then the body 91 has to be assembled again. This is an inconvenient, time-consuming, and also dangerous process, as there may be some residual BBs left inside.

SUMMARY OF THE INVENTION

A major objective of the present invention is to provide an ammunition supply device capable of convenient and speedy cleaning and maintenance.

Another major objective of the present invention is to provide an ammunition supply device so as to prevent accidental discharge from remaining BBs left in the toy gun.

Yet another major objective of the present invention is to provide an ammunition supply device so as to increase the number of repeated firings of BBs.

To achieve the objectives, the ammunition supply device is detachably plugged into a chamber inside a toy gun's body. The chamber stores an increased number of BBs. The body has a feeding opening connected to the chamber. The ammunition supply device contains a transmission module and a loading module interacting with the transmission module. BBs are supplied to the toy gun through the feeding opening into the chamber. The transmission module engages the loading module to load BBs for firing by the toy gun. After firing, the ammunition supply device can be easily taken out of the chamber through the feeding opening for cleaning or maintenance. In the meantime, it can be easily assured that there is no BBs remained in the toy gun so as to prevent accidental discharging. With the present invention, the prior arts' problems such as small capacity for BBs, and the troublesome and dangerous resupply of BBs are resolved.

The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

FIGS. 2A and 2B depict a toy gun incorporating the present invention. As illustrated, the toy gun does not have a magazine. As further shown in FIGS. 3 to 6, an ammunition supply device 2 according to an embodiment of the present invention is detachably plugged into a chamber 11 inside the toy gun's body 1. The chamber 11 is separated from the rest of the body 1 at least by a partition plate 12. The ammunition supply device 2 has a bullet inlet 24 open to the chamber 11 and a bullet outlet 25 connected to the bullet inlet 24. The ammunition supply device 2 contains a transmission module 21, a loading module 22 interacting with the transmission module 21, and a gathering module 23 interacting with the loading module 22. The gathering module 23 has at least a vibration member 231 on at least one side. The loading module 22 has at least a forwarding member 221 on at least one side. The transmission module 21 contains at least an elastic element 211, and is partially exposed out of the chamber 11. The body 1 has a feeding opening 13 connected to the chamber 11, and the feeding opening 13 is covered by a removable cover 14. The cover 14 has at least a buckle 141 on at least one side. The toy gun's BBs are stored in the ammunition supply device 2 and the chamber 11 without a magazine. The toy gun therefore closely resembles a real rife.

The operation of the present invention is described as follows, as shown in FIGS. 2A to 11. As illustrated in FIG. 7, BBs 3 are supplied to the toy gun through the feeding opening 13 into the chamber 11. As illustrated in FIG. 8, the feeding opening 13 is then sealed by the cover 14 which is locked by the buckle 141. To store the energy for firing the BBs 3, the exposed part of the transmission module 21 is twisted as shown in FIG. 9. The elastic element 211 then stores the kinetic energy for firing and loading the BBs. As the elastic element 211 releases the stored energy, the transmission module 21 is engaged. The transmission module 21 in turn engages the loading module 22, which in turn engages the gathering module 23. As shown in FIG. 10, the BBs 3 stored in the chamber 11 moves automatically towards the bullet inlet 24 due to gravity and then enters the ammunition supply device 2. Then, as the transmission module 21 operates, the gathering module 23 is turned as well. In the meantime, the vibration member 23 causes the BBs 3 to have slight movement and vibration through contacting with them so that the BBs 3 do not jam. The forwarding member 221 on the loading module 22 forces the BBs 3 to move towards the bullet outlet 25 for firing. As shown in FIG. 11, after firing, the ammunition supply device 2 can be easily taken out of the chamber 11 through the feeding opening 13 after removing the cover 14 for cleaning or maintenance. In the meantime, it can be easily assured that there is no BBs 3 remained in the toy gun so as to prevent accidental discharging.

Another detachable ammunition supply device 2 a according to another embodiment of the present invention is shown in FIG. 12. As illustrated, the ammunition supply device 2 a contains a transmission module 21 a which is automatically powered by a power module 212 a without manually twisting the transmission module 21 a as described in the previous embodiment.

Compared to the prior arts, the present invention has the following advantages.

Firstly, the ammunition supply device can be conveniently disassembled from the toy gun so that quick cleaning, speedy maintenance, and enhanced safety are achieved.

Secondly, the significantly increased bullet capacity of the toy gun is achieved jointly by the chamber and the ammunition supply device.

Thirdly, with the chamber and the ammunition supply device, the toy gun does not require a magazine and therefore can highly resemble a real, old-fashioned rifle and therefore achieves better customer attraction.

While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
